Material examined. – Holotype. Male ( LMBC), Philippines, Mindanao, 30 km W of Maramag, Bagongsilang, 1700 m, coll. Bolm, 13–17 Apr.1996.

Differential diagnosis. – M. ellipticus is very similar in general appearence and coloration to other species from the Philippines. Metanoeus ellipticus can be easily distinguished by the shape of the male genitalia, which are characteristic in the ellipsoidal shape of the apical part of the phallus (Figs. 9–10).

Head, pro- and mesothorax light brown, metathorax dark brown, pronotum and elytra bright yellow; antennae brown; trochanters and bases of femora light brown, gradually changing to dark brown apically. Head small, hypognathous, including eyes slightly wider than frontal margin of pronotum. Eyes hemispherically prominent, eye diameter 1.12 times frontal interocular distance. Antennae robust, flabellate, lamellae of median antennomeres about 3.1 times longer than body of antennomere. Head and antennae with dense, short, recumbent pubescence. Pronotum flat, 1.2 times wider than long at midline, widest at basal third. Posterior margin of pronotum bisinuate. Elytra almost parallel-sided, 4.26 times longer than width at humeri; slightly widened posteriorly, widest at apical third. Legs compressed, with dense pubescence. Male genitalia with oval-shaped, wide phallobase, phallus constricted in middle, ellipsoid apically (Figs. 9–10).

Measurements. – BL 8.6 mm, PL 1.22 mm, PW 1.46 mm, HW 1.7 mm, Edist 0.54 mm, Ediam 0.61 mm.

Distribution. – Philippines: Mindanao.
